aving thus described my invention what I claim as new and desire tosecure by Letters Patent is:

A rotary pump, including an intake and outtake equipped casing havingcommuni- Veating compartmental chambers, one of said chambers having ahollow cylindrical pumping member arranged therein, said latter memberbeing of less diameter than said chamber and having a downwardlyextending baiie, said casing having an opening receiving said bafe anddivided into an inlet andv an outlet passage thereby, the otheroompartmental chamber having a bracket with upwardly extending walls, atubular member with closure covered ends projecting through said casingand having an elongated slot` co-extensive with the interior of thechamber containing the cylindrical pumping member, said tubular memberbeing superposed upon the upper ends oit' said bracket-walls, a secondtubular member arranged within the aforesaid tubular member and having aslot extending entirely therethrough and co-extensive in length with theslot oi the aforesaid tubular member but of less width than said slot,said baffle-member extending downwardly through the slot of said secondtubular member, and into a chamber of said bracket to provide fortheoscillation of said baliie-member during the pump-operation, saidbracket walls subdividing the lower compartmental chambers intoadditional sub-chambers, in communication with the intake and outtake ofthe casing and a driving shaft for and coperating with saidpumpingmember.

ln testimony whereof I aiix my signature in the presence of twowitnesses.
